To all whom it may concern:

Be itknown that I, JoHNF. Wms'rmsn,

'a-citizen of the United States, residing at Another objector this invention is to r0 vide a pair of clrcumferentially exten ing hoops adapted for opposite placement upon opposite sides of the tire an having a plu rality of spaced apart eyes disposed around the peripheries thereof, the said eyes be ng oppositely disposed and connected by lln chains passing transversely over the tire to prevent skidding of the same.

Another object is the provis on of a pair of hoops, each of which'eomprises hingedly connected sections adapted to be folded one upon the other when the device 18 not. in use and the whole device reduced in slze so that it maybe stored in a tool box A still further object is to provide in connection with the free ends of the hingedly connected sections means whereby the device may be adjusted to fit wheels of various sizes. A With these and other objects in view the invention consists in combination of the various parts as w1ll be hereinafter described and pointed out in the appended claim. v

Application filed July 11, 1918. Serial No. 108,600.

therewith. A hoop 2' extends circumferentially of the tire and consists of a semicircular section 3, hingedly connected at 5 and 6 to a pair of sections '3 and 3", the

free ends of whichare reduced and threaded, as at 7 and 8 for the reception'of a turn buckle 9. -A hoop 4. is disposed upon the opposite side of said wheel and comprises a pair of semi-circular sections 4 and 4 hingedly connected at their meeting ends in the same manner and having thelr free ends provided with eyes 12 and 13 whereb the said free ends may be connected througli the medium of a cam lever latch 14: adapted to draw the said free ends together in a manner clearly illustrated in Fig. 3 of the drawings.

' 4 upon the opposite side of the wheel is also plurality of oppositely disthe said eyes 10 and 10' beprovided with a posed eyes 10; ing connected by link chains 11 transversely overlying the tire tread and'adapted to prevent the wheel from skidding.

While I do not wish to be strictly confined to the use of chains, I prefer them because theyserve as an excellent anti-skid element and at the same time they permit one func- As isshown in Fig. 3, the cam lever 14 is provided witha handle 15 adapt d s tion which is peculiar tot is invention, and which w ll now be described. Let us assume that the device is attached to a wheel on an automobile as in Fig. 1, with'thehoop 2' on the outer side of the wheel and the hoop 4next the body. When it is'desired to remove the device, obviou'slythehoop 4 must that its ends can be moved across the axle. This is accomplished by sliding the sleeve 16 back on the section 4; until the handle 15 is free, and then swinging the handle and thecam lever'around the eye 12 until they canbe drawn out of the eye 13. The ends of the sections 4=- and 4" are now free, and this-hoop can be moved to pass its ends astride the axle and to take'it from inside the wheel. Ofcourse if the other hoop 2' had been insidethe wheel it could be removed by running oil the turn buckle 9 and passing the free endsastride the axle. either case, however,-having removed the In I hoop from the inside the hoop on the outside is easily taken off because there is nothmgin the way but the outside of the hub.

' space. The hinge connections and 6 of the hoop. 2' are directly opposite the-hinge connections and the connection of Fig. 3 of thehoo 4 and therefore when the hoop 2 is folde the hoop-4 can be similarly folded, the chains 11 ermitting. The entlre structure is now re uced in size so that it can be packed away in a tool box or under a seat in small compass. When the next occasion arises where it is to be used, it is taken from its place and put back onto the wheel in the same manner. v

What I claim is In an anti -skid device for automobile wheels, the combination with a hoop adapted to lie against one side of the tire and made up of sections hmgedly connected wlth 'each' other at diametrically opposite points,

one section being subdivided into smaller sections, and means for detachably and adjusta'bly connecting the meeting ends of these smaller sections; of another hoop adapted to lie against the opposite side of the tire and made up of two semi-circular sections, means for hingedly connecting these sections at one end ata point opposite one of the hinge connections of .the firstnamed hoop, means for liingedly and detachably connecting the same sections at their other ends at a point opposite theother hinge connection of the first-named hoop, and flexible'elements connecting the hoops at points opposite each other and passing over the tire tread, as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
